After audio is disembedded, the audio processing path includes an A/B mixer and two voice-
over processors. Audio is re-embedded in program and preview audio after processing. (See the
detailed model, following.) Voice-overs are either stored EasyPlay clips or from external AES
input.
Detailed Model
This diagram shows a more detailed view of the LGK-3901’s video processing:
Each input (A, B, Key2, Fill1, and Key1) can be individually selected as an SDI input or one of 4
test signals. (Each SDI input can be subject to a rectangular clipping mask.)
Both the A and B side of the A/B mixers can connect to any of the inputs.
The LGK-3901 has storage (up to 8 GB) supporting internal keyers. Input B can be used, alterna-
tively, as the fill of an external key (fill2, key2). Either of the 2 external (fill, key) inputs can be
used to receive Intuition XG clips.
The preview output can present video from one of several different tap points.
Audio is disembedded from SDI sources, sent to the audio processing pipeline, and re-
embedded on output. The audio is re-embedded in the PGM and PVW outputs.
DSK-3901
The DSK-3901 (called a “3G/HD/SD Downstream Keyer”) can be considered a reduced version of
the LGK-3901. (If you order the right upgrade options, it will have the same features as an LGK-
3901.)
The DSK-3901 has the same “black box” diagram as the LGK-3901:
